“On occasion, we manually import quite a few data sources at once. These data sources are handled by business teams and can often induce errors that impact some key tables. One time, Looker was showing the wrong amount for some critical bills, everything was double or triple what it was supposed to be. There wasn't a specific logic to it, making it quite difficult to debug. Sifflet caught the issue by sending us an alert on Slack, pointing us directly to the root cause, and it took us 30 minutes to understand and solve the problem. Without Sifflet, we would have spent countless hours going through the 30 external sources one by one and trying to figure out where the anomaly came from.”
